LiDAR Engineering

LiDAR (Light Detection And Ranging) has become an established method for collecting very dense and accurate elevation values. This active remote sensing technique is similar to radar but uses light pulses instead of radio waves.

LIDAR being an active remote sensing system utilizes a laser beam as the sensing carrier. Laser scanners measure three-dimensional points on the surface of the earth. A platform (tripod or vehicle mounted) has a laser ranging system along with other equipment including a precision GPS receiver. The platform is moved around the area in which data are to be collected while the lasers utilized in this process typically emit millions of pulses per second. The travel time of these pulses is timed and recorded between the platform and the object along with the position and orientation of the platform to determine range.

The X,Y,Z measurements from the scanner are recorded and displayed as a "point cloud" which can be viewed, measured and navigated as a 3D model providing incredible insight to the project site. Precise elevations are derived from the point cloud data.

Use of LiDAR or laser for topographical mapping and contour generation is fast gaining acceptance worldwide. The commercial application of ground based laser scanning has proven to be a fast and accurate technology for information extraction.

To manage and operate this fleet, Genesys has deployed a large team comprising of Domain experts, Logistics Managers, Captains, Navigators, Drivers and Field Survey professionals. Additionally, for data processing, feature extraction and Map/CAD output generation a competent team with skills in both industry standard and proprietary software has been deployed.

Genesys offers the following services and deliverables for Mobile LiDAR survey and mapping requirements:

By sweeping a laser beam over a scene or object, the laser scanner is able to record millions of 3D points. These X,Y,Z measurements can be imported into 3D application software and displayed on a computer monitor as a "point cloud" which has photographic qualities portrayed in one-color, gray-scale, false-color or even true color. Since all laser scan points are 3D, the files can be viewed, navigated, measured and analyzed as 3D models.

Genesys has gained significant experience in executing Terrestrial LiDAR survey and mapping projects over the last few years. Genesys has successfully used this technology to execute projects in the Infrastructure vertical.

Aerial LiDAR typically involves scanning from an airplane or helicopter fitted with suitable laser scanner and is usually carried out for mapping large areas.

Genesys partners with expert Aerial LiDAR survey companies for aerial laser scanning and have an in-house team of experienced aerial LiDAR processing professionals. Genesys has rich experience in aerial LiDAR for carrying out wide area surveys for Mines, Forests, city and corridor surveys for Power lines, Roads, Railways, Coastline and Pipeline.
